It’s not just droplets: a systematic review and meta-analysis of the modes of transmission of Group A Streptococcus

The transmission of Group A Streptococcus (Strep A) through respiratory droplets has been considered the dominant mode of transmission to date; however, little is known about the relative contribution of other modes of transmission. This review systematically summarises the contemporary evidence regarding the transmission of Strep A.
